Chemical Structure
Description
Di-n-pentyldiphenyltin (CAS 23396-45-4) is a high-purity analytical reference standard with the molecular formula C22H32Sn and a molecular weight of 415.20 g/mol.
Structurally, Di-n-pentyldiphenyltin (C22H32Sn) contains a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 415.20 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Di-n-pentyldiphenyltin meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
